Propranolol may cause harmful effects for the baby if taken during pregnancy; [7] however, its use during breastfeeding is generally considered to be safe. [8] It is a non-selective beta blocker which works by blocking β-adrenergic receptors. [2] Propranolol was patented in 1962 and approved for medical use in 1964. [9]
A few drugs such as alcohol are absorbed by the lining of the stomach, and therefore tend to take effect much more quickly than the vast majority of oral medications which are absorbed in the small intestine. Gastric emptying time can vary from 0 to 3 hours, [2] and therefore plays a major role in onset of action for orally administered drugs ...
The WHO Model List of Essential Medicines for Children (aka Essential Medicines List for Children [1] or EMLc [1]), published by the World Health Organization (WHO), contains the medications considered to be most effective and safe in children up to twelve years of age to meet the most important needs in a health system.
Adrenergic antagonists reverse the natural cardiovascular effect, based on the type of adrenoreceptor being blocked. For example, if the natural activation of the α 1 -adrenergic receptor leads to vasoconstriction , an α 1 -adrenergic antagonist will result in vasodilation .
The first beta blocker, propranolol, was introduced in the early 1960s by the winner of The Nobel Prize in Physiology or Medicine 1988- Sir James W. Black. [23] The drug was originally developed in order to induce a calm effect on the heart by blocking the beta receptor for adrenaline, treating a range of cardiovascular disorders. [23]
First-pass metabolism may occur in the liver (for propranolol, lidocaine, clomethiazole, and nitroglycerin) or in the gut (for benzylpenicillin and insulin). [4] The four primary systems that affect the first pass effect of a drug are the enzymes of the gastrointestinal lumen, [5] gastrointestinal wall enzymes, [6] [7] [8] bacterial enzymes [5] and hepatic enzymes.
